In this paper, classical multidimensional scaling (MDS), which gives a geometric interpretation to input dissimilarity data, is used to classify 180 sulci drawn from the ten major classes of sulci. Using a leave-one-out validation strategy, we acheive a success rate of 100% in the best case and 78% in the worst case. For these more difficult cases, we propose a second stage of classification using shape based features. One of these features is the geodesic distance between sulcal curves obtained from a new open curve representation in a geometric framework.\r\nWith MDS, we offer a simple and intuitive approach to a challenging problem. Not only can we easily separate left and right brain sulci, but we also narrow the classification problem from, in this case, a 10-class to a 2-class problem. More generally, we can identify a region-of-interest (ROI) within which one can carry out further classification.","license":"You are licensing your work to Kitware Inc. under the\nCreative Commons Attribution License Version 3.0.\n\nKitware Inc. agrees to the following:\n\nKitware is free\n * to copy, distribute, display, and perform the work\n * to make derivative works\n * to make commercial use of the work\n\nUnder the following conditions:\n\\\"by Attribution\\\" - Kitware must attribute the work in the manner specified by the author or licensor.\n\n * For any reuse or distribution, they must make clear to others the license terms of this work.\n * Any of these conditions can be waived if they get permission from the copyright holder.\n\nYour fair use and other rights are in no way affected by the above.\n\nThis is a human-readable summary of the Legal Code (the full license) available at\nhttp://creativecommons.org/licenses/by/3.0/legalcode","keywords":["labeling","cortical"],"authors":[{"name":"Mani, Meena","email":"memani@irisa.fr","affiliations":["INRIA/INSERM, Visages Project, IRISA, Rennes, France."],"corresponding":true},{"name":"Srivastava, Anuj","affiliations":[]},{"name":"Barillot, Christian","affiliations":[]}],"date_submitted":"2008-09-12 11:41:14","external_publication_id":634,"revision_cids":["bafkreihbnt4dhre3r642uu7r66zmpqu4o2ndontdwpmnl4dioxydqxjg7q"],"thumbnail":"https://pub.desci.com/ipfs/bafkreif4fv4xmwvs2wzwyk6d5ho6yhi6tvql2gymmonytqqiqagjdipm2u"},"mdast":{"type":"root"},"downloads":[{"url":"https://ipfs.desci.com/ipfs/bafkreiborieepbn5jg3pw6qqyhlgzg4vxjux7aupzkt37efdu77t2ggvta","title":"root/insight-journal-metadata.json","filename":"insight-journal-metadata.json","extra":{"size_bytes":6157,"type":"file"}},{"url":"https://dweb.link/ipfs/bafybeidkdbb2x23iu7pkgthqwto73iippdiitdjnzoolkdd25ljbbdltpa","title":"root/article.pdf","filename":"article.pdf","extra":{"size_bytes":2017305,"type":"file"}}],"references":{"cite":{"order":["ref1","ref2","ref3","ref4","ref5","ref6","ref7","ref8","ref9"]},"data":{"ref1":{"label":"ref1","enumerator":"1","url":"https://doi.org/10.1038/385313a0","html":"A tension-based theory of morphogenesis and compact wiring in the central nervous system+Nature+385+6614+1997+313+318+Van Essen+D.:"},"ref2":{"label":"ref2","enumerator":"2","url":"https://doi.org/10.1109/42.764891","html":"Automated extraction and variability analysis of sulcal neuroanatomy+IEEE Trans.
